CARRlAGE-POLE.

SPECIFICATION forming part of Letters Patent No. 366,442, dated July 12,1887.

Application tiled March 1, 1887. Serial No. 229,362.

To all whom it may concern.-

Be it known that we, MiToHELL H. WooD- HULL and CHARLESllI. BLYDENBURGH, of Riverhead, in the county of Sufi'olk and State of New York, haveinvented certain new and useful Improvements in Carriage-Poles; and we do hereby declare the following to be a full, clear, and exact, description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object ofthis invention is to improve the vehicle-pole described in patent of the United States, No. 287,412, hearing date October 30, 1883.

I 5 It consists in providing the tongue or straight portion of the pole A with arms sufficiently rigid and strong to withstand the great strain to which the arms in this class of poles are subjected, and, while avoiding the making of the arms large and heavy, retaining sut'ficient elasticity and range of variation at couplingeyes to make a practicable adjustable pole.

In the accompanying drawings, Figure 1 represents top view of pole complete. Fig. 2

2 5 represents side view of pole. Fig. 3 represents pole in cross-section at E E.

To accomplish the desired result we use the straight or tongue portion A, (preferably of wood,) and divide or split it at its rear end a distance of about one (1) foot, and to each of such split or stub ends A we secure the larger end of hollow or U-shaped metal arms B by means of bolts or rivets C.

(No model.)

lhe arms 13 are made of metal formed hollow, but preferably U-shaped, and are pro- 5 vided at their free or rear ends with couplingeyes D. By the armsbeing made ofmetal and of the shape of a U we get the maximum strength with the minimum weight and size.

As will be seen, the metal arms B are light, very rigid, and of small initial cost; butby attaching them at one end to the divided or stub ends of the tongue or pole A sufficient elasticity is available in the divided ends A to give the arms B at their eye ends D a greater range of variation than is usually required in an adjustable pole.

Having described our invention, what we claim, and desire to secure by Letters Patent, 1s

1. In an adjustable vehiclepole, the straight or tongue portion split 01' divided at its rear end, said ends provided with hollow metal arms, substantially as set forth.

2. In an adjustable vehicle-pole, the eombi- 5 nation, with the stub ends of tongue A, of U shaped metal arms B, provided with couplingeyes D, substantially as set forth.
